\'Spiritual knowledge is not given to us as in ancient times. By spiritual means it must be struggled and striven for against a host of demons...We must therefore get to know the powers that would cover up and obscure all spiritual knowledge.\' - from the Preface \'The world seems to be standing within a demonic storm that threatens to overwhelm it\', states T.H. Meyer at the outset of this rousing call for a wide-ranging, spiritual-scientific knowledge of the world. Appeals to traditional religious belief will no longer pacify this storm, and neither will \'good will\' suffice. Building on Rudolf Steiner\'s anthroposophy, In the Sign of Five tackles the central task of our epoch: the epistemological struggle with evil, and presents the five most important spiritual events since the beginning of the Age of Michael: 1879 - the rise of Michael to the rank of Time Spirit; 1899 - the end of Kali Yuga; 1933 - the appearance of Christ in the Etheric; 1998 - the assault of Sorath, \'one of the greatest ahrimanic demons\'; The present - the incarnation of Ahriman. These events are linked to the five main tasks of the Age of Michael, the great challenge of inner knowledge and spiritual consciousness posed by the epoch as a whole. In the light of world history, and within the context of \'the sign of five\', we stand today at the fifth place - at the point of the incarnation of Ahriman. Is humanity prepared for this decisive event? Have we recognised the phenomena of evil that surround us on a daily basis? Have the tasks corresponding to the five events been identified, and to what extent have they been carried out? How is evil related to \'the good\' that guides the world, and specifically to the Christ impulse? Meyer provides a vital, pithy, aphoristic handbook for our apocalyptic times.
